Abstract: 615,897. Actuating machines. PEGARD, M. July 2, 1945, No. 16757. Convention date, Jan. 31, 1942. [Class 83 (iii)] An indicating device for a boring or like machine tool comprising a number of charts and indexing members associated with the charts, movable by the setting of the machine tool control levers, is characterised in that said charts are provided with rows and columns and that indexing members actuated by certain of said control levers designate the rows while other indexing members actuated by other control levers designate the columns of the charts. The indicating device as applied to a horizontal boring, facing and milling machine comprises a plate e having two windows. A polygonal member a, Fig. 2, rotatable behind the left-hand window, has marked on each face a series of diameters in three columns and six rows, the latter being of alternately different colour, for example red and blue. An adjusting knob c is secured to the end of the shaft carrying the indicator a, and adjacent thereto is a further indicator with the same number of faces as that of the member a, but showing only a single cutting speed on each face. The machine has eighteen different spindle speeds selected by three levers L1, L2, L3, the last lever is also used in selecting feed ratios and is linked at o to a horizontal pointer g which points to a pair of rows. The lever L2 indicates the column to be read, and the lever L1 indicates by means of the coloured marks m and n which of the two rows, indicated by the pointer g, is to be used, thus the levers are arranged according to the work or spindle diameter shown through the window to give the cutting speed shown by f. The right-hand window, in conjunction with the levers M1, M2 and L3, is adapted to give the lever positions for various feeds shown through the window. A mask is employed moved by a cam v on the member a to exclude one of each of the three pairs of columns of feed speeds according to the position of the member a.

Title: Machine for encasing sausage and the like
IPC: A22C11/02
Filed: 1964-04-22
Abstract: 1,048,141. Sausage machines. TOWNSEND ENGINEERING CO. April 22, 1964 [April 22, 1963], No. 16770/64. Heading A2B. In a machine for making sausages or like products wherein a succession of casings are continuously and automatically stuffed with a plastic or emulsion filling and formed into a series of discrete links joined by twists in the casing, which links are subsequently looped by the machine on a synchronised conveyer so that the loops each contain a predetermined number of links, each casing is filled with the filling under pressure so that the casing is distended into contact with a rotating chuck through which it passes, so as to be rotated thereby, the filled casing issuing from the chuck being gripped to prevent its rotation and crimped in synchronism with the conveyer, thus forming a twisted link at the crimped part. Fig. 1 shows a plan view of a suitable machine, Fig. 10 (not shown) shows details of the rotating chuck and gripping and crimping mechanism, and Figs. 12 and 19 (not shown) show means for looping the linked products on to a hook conveyer. A stuffing horn 26 having positioned on it shirred casing 108 supplied from hopper 17 is supplied with filling under pressure by means of conduit 18 and pump 16. The filled casing is gripped by rotating chuck 48 and the casing on leaving the chuck is guided by lugs 78 on chain 76, which prevents the casing from collapsing or deviating from a straight path. At intervals crimping lugs 80 progressively pinch and crimp the casing, whereby twisted links are formed at these sites. On leaving the chain guide 76 the linked product enters a rotating helical looping device 90, driven through gearing 88, which loops the product over hooks 79 on conveyer 81 driven by sprocket 83. The speeds of the meat pump 16, rotating chuck 48, chain guide 76, looping device 90, and conveyer 81 are all inter-related, for example by being driven by suitable gearing, which may be variable, from a single drive source, whereby the sizes of the individual linked bodies may be kept uniform at a desired value, and the number of links to each loop on the conveyer is maintained at any desired value. Means involving sensing switches and pneumatic or motor devices are provided such that when one casing has been filled, the stuffing horn 26 is withdrawn, thereby permitting another casing to come into position from hopper 17, after which the horn enters the casing and the process recommences. During this, flow of meat from the pump is cut off due to withdrawal of entry port 28 on the stuffing horn. Cut out and delay devices may be fitted to permit cycle completion. The product may be smoked prior to packaging, for example by extending conveyer 81 through a smoke house.

Title: Improvements in torque amplifiers for indicating, measuring, or regulating instruments
IPC: G01L7/00
Filed: 1933-06-13
Abstract: 425,599. Mechanical relays ; followup devices. BENDIX AVIATION CORPORATION, 105, West Adams Street, Chicago, U.S.A. June 13, 1933, No. 16863. Convention date, June 14, 1932. [Class 118 (ii)] In a device for amplifying the torque communicated to the driven element, such as the pointer, of an indicating, measuring, or regulating instrument by the movement of a sensitive element 7, a distributer 52 rotated by the sensitive element directs a jet of fluid against an impeller 41 which is caused to rotate and follow-up the movement of the distributer, this follow-up movement being used to actuate the driven element. As applied to an altimeter, Figs. 1, 2, the pressure-sensitive capsule 7 operates a rock shaft 11 carrying a segmental gear 15 which operates a pinion 16 on the shaft 17 of the distributer 52. A driven shaft 18 is connected through gearing 22 with pointers 19, 20 moving over a scale 21. The distributer 52 is in the form of a frustrum of a cone and has two apertures 53, 54 in its periphery whereby jets of air are directed against an impeller 41 carried on a plate 35 rotatable on the ball bearing 49. A displacement of the distributer causes rotation of the impeller by one of the jets which rotation is transmitted through a spur gear train 37-40 to a planet pinion 33 which climbs on a fixed gear 32. The plate 35 thus follows up the movement of the shaft 17. A sun gear 50 connected to the plate 35 operates a pinion 51 on the shaft 18. The plate 35 is of hour glass formation and has a weight 56 to balance the spur gear train. Stops 58, 59 on the plate 35 coact with a stop 60 on the distributer to prevent undue relative movement. Air pressure is supplied through a nipple 55, or air is exhausted through the opening 61 by means of a Venturi tube so as to cause air to be sucked through the nipple 55 and thus operate the impeller. The whole device is mounted in a suitable casing 4 and the pressure-sensitive element 7 is separated from the air pressure operating the impeller by a plate 6 which carries the gear 32 and receives the shafts 17, 18. Another plate also supporting these shafts carries the scale 21. The pointers may themselves operate auxiliary apparatus or may be replaced by controlling devices. Thus the pointer shaft 27 may operate a butterfly valve controlling the air supply to a supercharger. Specification 388,085 which relates to means whereby the movements of a compass or other turn-responsive device are communicated to an indicator at a distance, is referred to.

Portions T (Fig. 1, not shown) of tea or other material to be packaged are carried on the underside of the bottom run of a conveyer B by suction applied through spaced groups of orifices H. The material is subsequently enclosed in a tube formed from a web 12 and the tube is then divided into sections each containing one of the portions and having its ends sealed. In the machine described tea is conveyed along a passage 4 to the conveyer by a stream of air evacuated through the holes H and a suction box 5 behind the conveyer. Each heap of tea is levelled by a spinning disc 6 and the heaps of tea subsequently fall on to a partly tubed portion 10 of the web 12 conveyed by a belt 11 which is also troughed. One margin of the tube is then folded over by guides 21, and adhesive is applied to the inside of the remaining margin by a disc 22, the tube is completed by a folding guide 23, and the adhesive is activated by a heater 24. Rollers 27 then seal together opposite walls of the tube, at positions where they have previously been printed with adhesive by a wheel 14. The packets are subsequently cut at 28 from the web. The tea may be fed to the air passage 4 by a vibrating conveyer plate. The longitudinal seam of the tube may be formed by crimping instead of by adhesive.
